Problems solved by technology

However, with the application, obvious shortcomings have been exposed, such as too low bending strength and difficult construction
In addition to the above weaknesses, it also has poor impact load resistance, brittle texture, poor toughness, easy to cause crushing damage in harsh environments, easy to leak without excellent safety, and its wear resistance is also poor. The transportation of a large amount of gas and fluidized solids shows obvious deficiencies and potential safety hazards
Although the inventor overcomes the technical prejudice and introduces steel wire winding into the manufacturing process of thermosetting composite pipe for the first time, so that the bending strength and impact resistance are significantly improved, other performances, especially the further improvement of strength and weight reduction, and cost are still relatively low. work to be done

Embodiment Construction

[0013] The stencil resin composite layer in the present invention is the focus of the improvement of the present invention, and the improvement also includes the improvement of the composite adhesive curing agent formula used for the processing of each layer. The specific process structure composition includes fiber, fiber fabric or steel wire as the base material, and the composite adhesive curing agent is composed of thermosetting resin glue with flame retardant, antistatic agent, curing agent, accelerator and filler. The base material is wound on top while the compound adhesive curing agent is coated, and finally cured to form a pipe combined with prefabricated flange fittings. Inner liner 1 with anti-seepage or wear resistance formed by thermosetting resin binder with flame retardant properties, on the basis of flange mold and inner liner 1, reinforced fibers and fabrics are wound and steel wires are added at the same time The base material is a strength layer 2 formed by ...

Abstract

The invention relates to an anti-static fireproof light high-strength resin steel network composite tube and relative production. The tube comprises three layers as the liner layer with anti-leakage or abrasion-resistant function, a strength layer coiled by strength fiber and added steel base material, and a surface layer coiled with dense fiber at the face. The invention is characterized in that: 1, the composite adhesive solidifier of liner layer (1) is added with 5-10 deals of glass scales and / or 5-15 deals of graphite scales; 2, each 100 deals of resin of composite adhesive solidifier is added with 0.5-5 deals of antioxidant; 3, each 100 deals of resin of composite adhesive solidifier is added with 2-10 deals of short tangent fiber to form slurry composite adhesive solidifier coiled with the mesh steel wire to form the strength layer.

Description

technical field [0001] The invention relates to the improvement of the structural design and manufacturing process of the flammable gas, liquid or fluidized solid transmission pipe. It is especially suitable for the anti-static and flame-resistant light-duty high-strength resin steel mesh composite pipe required in underground mines and thermal power and steel industries. Background technique [0002] Many flammable and explosive occasions require large pipelines to transport gases, liquids, and even fluidized solids. The gas, liquid or liquefied solid transported by many pipelines is itself flammable and explosive, such as various pipelines in mines, such as underground air with high gas content, blast furnace gas, and fly ash. In this case, there are higher requirements for the transmission pipeline, such as flame resistance, anti-static phenomenon, wear resistance, anti-leakage, etc. Therefore, traditional engineering specifications can only use cast iron pipes, or larg...
